    Thirty-Six-Story Downtown Office Tower

    Sieben Energy Associates worked with management and the chief engineer of a multi-tenant office tower to maximize ROI from their upgraded building automation system (BAS). The energy-saving measures identified and implemented through retro-commissioning achieved immediate simple payback. Our entire project reduced annual energy use by 20% and cost by $150,000.

    Suburban Acute Care Hospital

    Sieben Energy Associates assisted the owner of a large medical center with participation in the local utility’s retro-commissioning incentive program.

The owner enjoyed better financial performance after a six-month simple payback.

    Consortium of Twelve Colleges and Universities

    Sieben Energy Associates consulted on electricity purchasing for a group of colleges and universities. We evaluated supplier RFP responses, recommended a buying strategy, and helped our client secure consecutive supply contracts worth a combined $25 million. By carefully timing both transactions, we helped the consortium avoid potentially millions of dollars in additional expense due to increasing power prices.

In just two years, management has nearly achieved the building owner’s commitment to a 20% energy use reduction over five years.
